    Hi Stoyan,<br>
    <br>
    I prefer Freeswitch, but I know that Asterisk can do prepaid and
    there are different prepaid solutions.<br>
    Anyway, as the prepaid server is a mission-critical component, I
    would like to have your (and the community) opinion about the
    preferred architecture and experiences about opensource/commercial
    solution (advantages and drawbacks).<br>
    All the billing solution are good enough for a service provider
    environment? How I can choose the right solution if all vendors say
    that their solution is the best one? :)<br>
    <br>
    Regards,<br>
    <br>

      <div>I mean you can use Kamailio and couple of Asterisk servers
        behind it to do prepaid. There are lot of prepaid solutions for
        Asterisk. But again, if I have to do it I will prefer my

                  <br>
                  I'm working in a project for a service provider in
                  which prepaid is an essential requirement. They have
                  about 12000 subscribers.<br>
                  The core infrastructure will be Kamailio+RTPProxy
                  while I have some doubts about the prepaid feature.
                  I'm thinking about a B2BUA (SEMS or Freeswitch) that
                  is called if the user belong to a "prepaid group" and
                  perform authorization and accounting; in this case the
                  SIP flow could be: Kamailio -&gt; B2BUA(Prepaid) -&gt;
                  Kamailio. Is a good choice?<br>
                  <br>
                  At the moment I cannot estimate the effort needed to
                  develop this section (base prepaid feature) of the
                  project... Do you have some hints?<br>
                  <br>
                  What are the prepaid solution implemented by you? Do
                  you use your own developed solution or do you think
                  that is better to choose a commercial solution (that
                  provide also calling-card and other features)?<br>
                  I have seen some commercial products (Portabilling,
                  Jerasoft/Bilberry, ...); what do you think about?<br>
                  <br>
                  <br>
                  Best Regards,<br>
